Oh, My Dear Darlin' Baby Jesus !!!
No. you never showed me that( and it was way too early in the day for Cocktail Time) and Yes, it's there. I never noticed it and then again... now that I know it's there, it certainly is not effective.
There is something about the "Spritzer" being on the Center of the Chamber that I found more effective then that "Slit".
After all... wasn't it Hobart that stated the theory "Either the Water has to move or the Dishes." ??? Well, engineering must have been on the last hour of design on a Friday or smoked some really good Kush when they came up with a "Slit" to replace the Constant Spritzer. . LOL. Yeah, you can't break that but I have seen similar gimmicks like in a Bosch if I'm not mistaken.
Even my KenWhirl with the Crappy Top Rack that I can't adjust to get Larger things like mixing Bowls and other Larger Vessels has a Dribbler on the top that manages to get most off. Not all... like the Original Constant on the 17 and 18 series KitchenAids that were Hobart Built.
I had used a RR a few times and liked it. I couldn't pass on a machine like the Jenn with practically no use. So it was there and I bought it. I know Ken is surveilling my house. LOL.
